“…In autumn or winter many bivalve species stop their growth e.g., due to reproduction, food availability or cold temperatures. This has also been reported for other species within the SMG, such as Panopea abbreviata and Ostrea puelchana (Morsan et al, 2010;Doldan et al, 2018). Finally, it is important to mention that an in situ 3 I8 O SW value for the SMG was of great significance since this gulf has its own special water dynamic, which differs from the open ocean (cf., Section 2) and shows little variation throughout the year.…”

Amiantis purpurata is a common warm-temperate water bivalve species distributed from southern Brazil to northern Patagonia, Argentina, which has a rich and well preserved fossil record in the San Matias Gulf (SMG) dating back to the late Quaternary. This study aims to establish A. purpurata shells as a new palaeoarchive of past marine conditions in South America. We compared the stable oxygen and carbon profiles (8 18 O,heu; 8 13 C S hcii) of eleven specimens of A. purpurata from different geological times (modem, Late Holocene and interglacial Late Pleistocene), and additionally present in situ oxygen isotope values of seawater within SMG (S ,8 O watcr ). Using both sets of information, we calculated and reconstructed palaeowater temperatures for the Late Holocene and compared them to modem water temperatures. Our findings indicate that A. purpurata records past environ mental parameters such as water temperatures on a seasonal scale and can therefore be considered a suitable candidate for future palaeoenvironmental reconstructions in Northern Patagonia. This study is the first step towards further stable isotope analyses on fossil A. purpurata shells, which will show whether and if so, to what extent, important global climate events such as the Neoglacial (Early Holocene), the Hypsithermal (Middle Holocene) and the Little Ice Age (Late Holocene) occurred in South America.

“…Other tropical species may be capable of building reefs subtidally, but this has not been documented in English literature. By comparison, four of the six temperate species are exclusively subtidal species [Ostrea angasi (Gillies et al, 2020), O. chilensis (Cranfield, 1979), O. edulis (Pogoda et al, 2019) and O. puelchana (Doldan et al, 2018)], and S. glomerata and O. lurida are capable of building reefs both subtidally and intertidally (Pritchard et al, 2015;Gillies et al, 2018). Despite the high diversity of tropical reefbuilding oysters that we identified, there is little evidence of extant remnant reefs in the tropics.…”

Oysters are ecosystem engineers that form biogenic reef habitats in shallow coastal and estuarine waters and provide important ecosystem services. Widespread global declines have triggered a world-wide restoration movement, however a paucity of information on tropical oyster reefs has resulted in their exclusion from existing global assessments and, consequently, restoration. In this review we quantified the known global diversity of native reef-building oysters to compare diversity between temperate and tropical regions and assessed historic oyster reef presence and declines using two tropical case studies. We then summarised the biology, ecology, and benefits of tropical oyster reefs, which have four functional differences to temperate reefs: 1) the diversity of reef-building oysters is over four times higher in tropical than in temperate regions; 2) tropical reef-building oysters can have continuous spatfall throughout the year whereas temperate species have a defined season; 3) tropical reef-building oysters are generally faster growing than temperate reef-building oysters; and 4) tropical oysters commonly create mixed-species oyster reefs whereas temperate oyster reefs are generally formed by a single oyster species. There is evidence of unsustainable and destructive harvesting that has resulted in the decline of tropical oyster reefs, and these reefs should therefore be included in restoration efforts. We highlight knowledge gaps that can guide future research to develop important foundational information that will remove barriers to tropical oyster reef restoration.
